Coast.e00 (100 km buffer along the ice-free coastline) is an ARC/INFO
interchange file. The file can only be used with Geographic Information
System (GIS) software, such as ARC/INFO, the file's native format, or by
importing it into another GIS software package.

Coast.e00 was calculated in Plate Caree equidistant cylindrical
projection. Distance was measured from the coast, excluding coastline in
the Arctic and sub-Arctic regions above the winter extent of sea-ice.
The source of winter sea-ice extent is: NGS (National Geographic
Society). 1995. /The World: Political/ (map). Washington, D.C. The
source of the digital coastline is: ESRI (Environmental Systems Research
Institute) 1996. /ArcWorld Supplement Data Reference and User's Guide/.
Redlands, California.

This GIS data was created as part of The Center for International
Development?s ongoing research into the role of geography in economic
development (see www.cid.harvard.edu/economic.htm)
<http://www.cid.harvard.edu/cidglobal/economic.htm>. It was created
between 1998 and 1999. Please reference CID if you use this data in a
